But, as a sandstorm moves in to blanket the area, the Americans are attacked by an overwhelming enemy force of EU soldiers in a surprise attack.
Forced into a deep cave system beneath the Martian surface, Cameron and the team uncover a breathtaking discovery, left untouched for millennia.
But what will happen when its original owners come back for it?
Will Cameron survive and be able to return to Earth?
